A US woman who shot and killed her husband and two adult children before taking her own life is thought to have committed the shocking crime as a result of being ostracised from the religion she was raised in.

Every time I tell a mate I’m doing a story on cryptocurrency, they invariably ask me the same two questions: should they invest their own hard-earned money, and which cryptocurrency will get them a Lamborghini/yacht/island quickest?

Qld Labor, LNP pass buck on Nuttall super

Queensland's politicians are buck-passing over corrupt former minister Gordon Nuttall's superannuation fund after it was revealed it may be too late to claw any money back.

Nuttall was released on parole on Monday after serving six years behind bars for corruption and he's believed to be sitting on a plush nest egg containing up to $1.2 million, partly funded by taxpayers.

Labor and Liberal National Party governments both failed to recoup any of the money while Nuttall was in prison.

Treasurer Curtis Pitt admits time limits to pursue the funds may have expired, but he's considering all possible options.

"If we can recoup any money, we will," he said in Cairns on Friday.

The issue triggered a blame game between Health Minister Cameron Dick and former LNP treasurer Tim Nicholls.

Mr Dick insisted the Bligh Labor government was unable to act until Nuttall's appeals had been exhausted in late 2011.
